One of my student's parents filled our aquarium with a crayfish, snails, tadpoles, etc. I don't think I will ever look at a crayfish the same way again. Definitely not as food.
Ours likes to "dance" when we play music. He presses himself against the front of the tank and wiggles his claws (legs?)
(Ok, thread hijack over.)
